Benefits of technology

[0003] The present invention attempts to address this and other needs by the surprising discovery that the use of certain formaldehyde scavengers in fabric care compositions, particularly those fabric care compositions that comprise perfume microcapsules, may reduce the level of free formaldehyde in the composition. Therefore one aspect of the invention provides a fabric care composition comprising a fabric softening active, a perfume microcapsule, and a formaldehyde scavenger. Methods of using the fabric care compositions of the present invention to treat fabric are provided. Kits comprising the fabric care compositions are also provided.

Problems solved by technology

However, some microcapsules contain formaldehyde or generate formaldehyde over time.
However, these microcapsules may emit formaldehyde.
Formaldehyde is very volatile, has a very unpleasant odor which irritates the eyes and nasal passages and may give rise to other health problems.

Abstract

Fabric care compositions comprising formaldehyde scavengers exhibit low levels of free formaldehyde.

Description

FIELD OF INVENTION [0001] The present invention relates to compositions comprising formaldehyde scavengers. BACKGROUND OF THE INVENTION [0002] Perfume microcapsules and the use of perfume microcapsules in fabric care compositions is known. See e.g., US 2003 / 0125222 A1. However, some microcapsules contain formaldehyde or generate formaldehyde over time. It is thought that the shell material used to manufacture the shell of the microcapsule may be responsible for the formation of free formaldehyde. For example, these shell materials include melamine-formaldehyde, urea-formaldehyde, phenol-formaldehyde, or other condensation polymers with formaldehyde. Nevertheless formaldehyde based resins such as melamine-formaldehyde or urea-formaldehyde resins are especially attractive for perfume encapsulation due to their wide availability and reasonable cost. However, these microcapsules may emit formaldehyde. There are several sources of this released formaldehyde, e.g., unreacted excess formal...
